。 The drive shaft has a gripping male threaded part at its tip that can be screwed into the gripping female threaded part formed in the segment.
A support tube that is movably supported only in the axial direction is provided so as to be movable in and out of the casing that opens in the gripping frame, and is attached to the drive shaft between the gripping male threaded portion and the support tube in the axial direction. At the same time, the threaded extrusion tube formed on the outer periphery of the extrusion screw tube can be freely engaged with the extrusion screw tube, which is freely movable. An extrusion female threaded part movable in the center direction is provided in the casing, between the extrusion threaded cylinder and the gripping male threaded part,
and the first one between the extrusion screw cylinder and the support cylinder.
and a second extrusion spring is interposed, a pullback spring is interposed between the base end of the drive shaft and the support tube, and the forward and reverse rotation is interlocked and connected to the support tube to rotate the drive shaft. 1. A segment gripping device in a segment assembly device, characterized in that it is provided with a rotary drive device.
